Sometimes we do complex stuff just for the sake of learning, and that's the essence of why we have home labs.
I built a Fedora container image (for an Ansible execution environment), from inside an Ubuntu container, that is running inside another Ubuntu container (Forgejo runner), while all of them were using the same underlying Docker-in-Docker, running from a Docker Compose (where Forgejo and the Runner also are), on a Debian base OS, on a Raspberry Pi.
Did I need to do that? Absolutely not. Did I like doing it? Obviously yes!
Now I just need to find the time and the head space to write a blog post about it. 😄
